Ash dieback

Protecting Ash Trees

The native ash is commonly found in the countryside as well as in many gardens, and is one of the top native trees along with oak, lime, willow, alder, birch, and hawthorn.

There are a number of other disorders of ash trees and therefore it is important that these are not mistaken for ash dieback disease. Please visit the Forest Research (external link) website for more information.
